This happens because Apple installed libedit using the name libreadline. It happens even
if you have the real GNU readline installed via [homebrew](http://brew.sh); since the homebrew
library will conflict with the one that is part of OS X, homebrew does not link the homebrew
version into any of the standard locations.
The article above suggests forcing homebrew to link the libs into /usr/local, installing the distro,
and then unlinking the libs. While this works, it represents a special case that is ugly to automate.
The attached patch to the Makefile.PL adds a bit of code so that if the platform is darwin and the user
hasn't explicitly specified include and library directories (either explicitly or indirectly via --prefix) then
see if homebrew will provide a prefix for that library (`brew --prefix readline`) and if so, use it to
set RLLIB and RLINC.
I think that the special case is worth including in the Makefile.PL because it enables automated builds
on OS X using the current mainstream tools (e.g. homebrew).
Thanks,
g.
